Patrick Napoleon was booked into the Tulsa County jail on complaints including assault and battery with a deadly weapon.

Napoleon was arrested on June 15, 2015, after police said he used a BB gun to try to rob a groundskeeper on the Unversity of Tulsa campus.

The case was dismissed when a prosecution witness did not show up for court.

He pleaded guilty to a second-degree burglary charge for breaking into a bank a few days before the TU incident. The judge gave him a three-year deferred sentence in that case.

On July 13, 2016, he pleaded guilty to resisting an officer. The gave him a one-year deferred sentence. The DA's office asked the judge to revoke it back in January, but the judge decided to wait to make a ruling until June 29, 2017 to give Napoleon more time to comply with the conditions of the sentence.
